Vegetation communities in this regional ecosystem include: 7.3.43a: Eucalyptus tereticornis open forest, tall open forest and woodland including communities ranging from those dominated by E. tereticornis to mixtures of that species with Corymbia intermedia, E. drepanophylla, Lophostemon suaveolens and Allocasuarina torulosa. Uplands on alluvium. Contains Palustrine. (BVG1M: 9e). 7.3.43b: Eucalyptus tereticornis, Corymbia intermedia, E. reducta, Allocasuarina torulosa open forest, tall open forest and tall woodland. Uplands on alluvium. Not a Wetland. (BVG1M: 9e). |

| Fire management guidelines | SEASON: Cool, dry season (June-Sep). a,b: After the wet season when rain is reliably expected and there is good soil moisture. Burning in the dry season (Oct-Dec) will give high intensity fires. INTENSITY: Low to moderate. a,b: Low to moderate with occasional high to control overabundance of tree recruitment in mid-stratum. INTERVAL: 2-5 years. a,b: 3-5 years for grassy understorey. 6-10 years for shrubby understorey. INTERVAL_MIN: 2. INTERVAL_MAX: 10. STRATEGY: Mosaic burn < 30%. Begin burning early in the fire season, with progressive patch fires burnt through the year. Stop burning when the network of fires and other breaks is sufficient to impede fire spread later in the year. Storm-burning may be used to add further diversity to the fire mosaic. a,b: Aim for a good fire coverage to limit forest transitioning. Do not target moist areas, such as in or near gullies as these will provide a mosaic of denser vegetation and refuge for some plant species. ISSUES: Ignition is most likely during hot, dry season (Oct - Jan). These fires are typically high intensity fires that can be difficult to control. Maintaining a fire mosaic will ensure protection of animal habitats and mitigate against wildfires. Fire management approach may be different south of Ingham and similar to areas west of Kuranda to Mt Molloy. a,b: High intensity fires can be used to control an over-abundance of mid-storey recruitment; once controlled return to normal fire regime. Follow-up fires may be required to control more advanced tree recruitment (e.g., of rainforest pioneers) and flushes of she-oak, acacia and hopbush. |
